Superliner

Core ideas

Superliner keeps your writing as notes that nest, open as pages and link to each other. A supertag says what a note is, a field says what it has, and a workspace keeps one set of notes in its own folder.

Notes and pages

A note is the unit of Superliner. It has text, can hold other notes under it, and can carry supertags and fields. Every note can also open as a page of its own. Click the note's bullet and the note becomes the page: its text is the title, its child notes are listed below, and its fields show under the title.

The page and the outline row show the same note. Editing the text in either place changes the one note, so there is no second copy to keep in step.

References

A reference puts one note in a second place. Paste as Reference, or choose Add Reference from the Note menu, and the note appears again where you put it. The reference is the same note, so its text and children are shared. The bullet of a reference shows a ring. Removing a reference takes it out of that place only, and the note stays where it is.

A note can therefore sit under a project and under a person at once, and it stays one note. See References for the steps.

Supertags say what a note is

A supertag answers the question “what is this?”. A note is a project, a person, a meeting or a task. A note can carry several supertags, and adding one does not remove the others. The supertag's name is shown as a chip after the note's text.

Supertags do not follow from fields or from position. Setting a field does not add a supertag, and nesting a note under another does not make it a project. You choose the supertag.

Fields say what a note has

A field is a named value on a note: Status: Active, Due: 3 November, Owner: Maya. A field has a type, such as text, number, date or option. The type decides how the value is edited and checked. A field can be added to one note, or come from a supertag that the note carries.

Open Tags and Fields with ⇧⌘T to see a note's supertags as removable chips, its fields, and the supertags you can add.

Workspaces hold separate sets of notes

A workspace is one self-contained set of notes. It has its own folder, its own supertags, fields and saved searches, its own Trash and its own undo history. Notes in one workspace are not visible in another.

The app remembers each workspace's open pages, history, sidebar and side-by-side pane. See Workspaces for creating, opening and switching between them.

How they fit

A note sits in a workspace and under a parent note. It opens as a page, carries supertags and fields, and can be referenced from other pages. Supertags and fields are notes too: a supertag opens its own page, which lists its fields and the notes that carry it. Saved searches are notes as well, so they open and can be shown in a view.

The Markdown copy in the workspace folder records the same notes, with their supertags and fields at the top of each file, for other tools to read.
